If shifts to the right and the left.

It shifts to the left.
It shifts to the left.

It shifts to either the right or the left

Answer 1

Disruptive selection typically leads to a distribution curve where individuals at both extremes (the higher and lower ends) are favored over those in the middle. This can result in the curve splitting into two distinct peaks or modes, with the middle showing a decrease in frequency.

Therefore, the correct response would be:

**If shifts to the right and the left.**
